Online rebate speed with Mac+Ipod promotion??

I'm planning on buying a Macbook + ipod touch and take advantage of the Back to School promotion.
I'll probably buy it by the end of June and I only have my apartment by the end of July, so basically I have one month for the rebate check to arrive at my home.
Will it arrive in time? How long have you waited for your rebate?
I plan to buy everything online, can I submit the rebate immediately after my purchase or do I have to wait until it ships/arrives home?

I've called Apple several times but each time they tell me a different thing. I just want to know the experience of people who have actually used the promotion!

I purchased my MBP and Touch on Monday, June 9th at a physical store. Filled out the web rebate form online the next morning. Monday, June 16th, I received an email that said my rebate was in the mail and should be in within 3-5 days. I checked my mail that same night and it was already in. Very quick and painless process.
